ADJUSTABLE GUIDE.

SECIFICATION forming part of Letters Patent No. 703,749, dated July 1, 1902.

Application vfiled April 23, 1902. Serial No. 104,342. (No model.)

To all whom it may concern.:

Be it known that I, EDWIN B. STIMrsoN, a citizen of the United States, residing in the borough of Brooklyn, county of Kings, and city and State of New York,have invented certain new and useful Improvements in Adjustable Guides, of which the following is a speci-v ication.

This invention relates to the general class of adjustable or shiftable guides or stops; and it has for its object to provide a simple guide which may be shifted along 'a guideway and set fast therein at any point desired.

In the accompanying drawings, which illustrate an embodiment of the invention, Figure l is a plan of the device. Fig. 2 is a side elevation thereof, partly in section. Fig. 3 isa perspective view of the device' detached.

In the drawings only so much of-the machine to which the guide is applied is shown as will be necessaryto illustrate the construction and operation of the latter.

A designates the bed or table of a machine,` in which is formed a slot or guideway a to re ceive the body or block of theguide.

l is a rectangular block which its in the guideway rather snugly, but freely or loosely, so that it may be moved along the same to the point desired. This block may be clamped fast at any point desired by means which will now be described.

In a recess 2, formed in one end of the block l, is movably mounted a clamping-plate 3, which has a stem 4, that is slidable in a bore 5 in the end of the block. This stem has on it an inclined shoulder at 6, adapted to be impinged upon by a screw 7, which has a conical tip. This screw is driven down through the top of the block, and its axisis at right` angles to the axis of the said stem.

When the block shall have been accurately adjusted to the desired position in the guideway a, the screw 7 is driven in, and its point or tip by impinging on the shoulder on the stem 4 forces the clamping-plate 3 out and puts its face intofrictional contact with the side wall a' of the guideway a. This effects the locking of the blockvin position in the guideway wherever set.

On the block l is the guide-plate 8, which projects out over the bed A, its lower edge 8a bearing thereon and sliding thereover in the adjustment of the block along the slot or guideway. This plate is secured to the face or side of the block-by screws, and it may extend out over` the 'bed to any desired ex-A tent.

The particular size and relative proportions of the block l are not important to my inven- Ition, as these may be varied to suit the cir- 6o cumstances and the particular kind of machine to which the invention is applied.

Preferably the edge 82L of the guide-plate will be parallel with the upper and lower faces of the block and be alined with the upper face thereof. The opposite ends of the block will be faced off square and be parallel with each other.

Having thus described my invention, I claim- 7o l. A guide comprising a block with squared ends, a clampingplate occupying a recess in oneendvof the block; andprovided with a shouldered stem slidable in the block, a screw witha conical tip set in the block and adapt-` ed to engage the shoulder on said stem, and a guide-platesecuredto said block and extending out therefrom parallel with the side of the block, substantially as set forth.

2. A guide comprising a block having 8o squared ends parallel with each other, a screw clamping device mounted in said block for securing it in position, and a guide-plate se cured to one side or lateral face of said block, the said plate extending out beyond the end 8 5 ofsaid block and having thelower edgevof said extended portion parallel with the upper and lower faces ofthe block, substantially as set forth.

3. The combination with a bed having a 9o guideway with parallel sides formed therein,

iof'alguide comprising a block with squared, parallel end faces mounted in said guideway,

a clamping device carried by said block for securing it fast in the guideway when adjusted, and a guide-plate carried by said block and extending transversely of the guideway, said plate extending out beyond the lblock and having its lower edge coincident with the surface of said bed, substantially as roo set forth.

In witness whereof I have hereunto signed my name, this 21st day of April, 1902, in the presence of two subscribing witnesses.

EDWIN B. STIMPSON.
